Why is it an investment for the cell to use two ATP at the beginning of glycolysis? END RESULT IS 4 ATP USING 2 AT THE FRONT GIVES A NET GAIN OF 2 AT THE END 3. Complete the diagram by writing on the lines provided the names and numbers of molecules used and produced during glycolysis.Ģ. How does an understanding of the process of cellular respiration support the theory that the cell is the basic functional unit of life? CELL RESP IS THE PROCESS BY WHICH ENERGY FOR LIFE PROCESSES IS OBTAINED FROM FOOD MOLECULES IT OCCURS IN THE SAME WAY IN ALMOST ALL CELLSĩ.2 The Process of Cellular Respiration Glycolysis 1. A Comparison of Photosynthesis and Cellular Respiration Aspectġ7. Complete the table comparing photosynthesis and cellular respiration. Photosynthesis takes place in nearly all life.ġ6. Cellular respiration removes carbon dioxide from the air.ġ5. Photosynthesis deposits energy in Earth’s “savings account” for living organisms.ġ4. The energy flow in photosynthesis and cellular respiration occurs in the same direction.ġ3. If the statement is false, change the underlined word or words to make the statement true.ġ2. Complete the illustration by adding labels for the three main stages of cellular respiration.Ĭomparing Photosynthesis and Cellular Respirationįor Questions 12–15, write True if the statement is true. Pathways that do not require oxygen are said to be ANAEROBIC. The pathways of cellular respiration that require oxygen are said to be AEROBIC. Cellular respiration continues in the MITOCHONDRIA of the cell with the KREBS and electron transport chain. At the end of glycolysis, about 90% percent of the chemical energy is locked in the bonds of the PYRUVIC ACID molecule. Cellular respiration begins with a pathway called GYLCOLYSIS, which takes place in the THYLAKOID of the cell. If cellular respiration took place in just one step, most of the ENERGY would be lost in the form of light and HEAT. The equation that summarizes cellular respiration, using chemical formulas, is 6O2 + C6H12O6 6CO2 + 6 H2O + Energy.Ħ. Overview of Cellular Respirationįor Questions 5–10, complete each statement by writing the correct word or words. Cells use the energy stored in chemical bonds of foods to produce compounds that directly power the cell’s activities, such as ATP. A Calorie is also referred to as a KILOCALORIE.Ĥ. The Calorie used on food labels is equal to 1000 calories. Release energy from food in the presence of oxygen?ĩ.1 Cellular Respiration: An Overview Chemical Energy and Foodįor Questions 1–4, complete each statement by writing the correct word or words. Organisms undergo the process of cellular respiration? Chapter 9: Cellular Respiration and Fermentation Cellular Basis of Life Q: How do organisms obtain energy?
